Static Electricity and Electrons (Part 3).
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
Energy never disappears — it just hides somewhere else.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Before you start: which will move faster, and why?
What You'll Learn
Static electricity builds up when objects gain or lose electrons through rubbing. Rubbing a balloon on your hair transfers electrons, making the balloon stick to a wall.
Key Words
Tap a word to see its definition.
Materials Needed
- ruler
- cardboard
- marbles
- paper clips
Safety First
- Do not taste any materials.
Steps
Look at the vocabulary words and write a definition for each in your own words.
Construct a catapult from popsicle sticks and rubber bands. Launch a marshmallow from different angles and measure the distance. Find the angle that gives the longest launch.
Draw a detailed diagram of what you observe.
Write a conclusion: what did your results show? Did they match your prediction?

Question 1
1 of 3What happens when you rub a balloon on your hair?
Where you see this in real life
You use this every time you flip a light switch, ride a bike, or kick a ball.
Stretch Challenge
Try this in real life this week.
Time how long a small ball rolls down something, then change the slope and try again.
For the dinner table
“Show me something at home that uses this kind of energy.”
